TOM40 as a prognostic oncogene for oral squamous cell carcinoma prognosis

BACKGROUND

To investigate the role of the translocase of the outer mitochondrial membrane 40 (TOM40) in oral squamous cell carcinoma (OSCC) with the aim of identifying new biomarkers or potential therapeutic targets.

METHODS

TOM40 expression level in OSCC was evaluated using datasets downloaded from The Cancer Genome Atlas (TCGA), as well as clinical data. The correlation between TOM40 expression level and the clinicopathological parameters and survival were analyzed in TCGA. The signaling pathways associated with TOM40 were identified through gene set enrichment analysis. A network of genes co-expressed with TOM40 was constructed and functionally annotated by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. The immune infiltration pattern in OSCC was analyzed in the TCGA-OSCC cohort using the CIBERSORT algorithm. Clinically significant factors of OSCC were screened through the expression levels of TOM40 and a clinically relevant nomogram was constructed. The TCGA-OSCC cohort was divided into the TOM40high and TOM40low groups and the correlation between TOM40 expression level and the sensitivity to frequently used chemotherapeutic drugs was evaluated. CCK-8 and colony formation assays were applied to determine the cell growth.

RESULTS

TOM40 was highly expressed in OSCC tissues and correlated negatively with the overall survival (P < 0.05). Patients with high TOM40 expression level showed worse prognosis. Furthermore, GO and KEGG enrichment analyses of the differentially expressed genes related to TOM40 showed that these genes are mainly associated with immunity and tumorigenesis. Immunological infiltration analysis has found that the expression levels of TOM40 are correlated with the proportions of several immune cells. Moreover, we found that TOM40 knockdown inhibited cell growth in OSCC cell lines.

CONCLUSIONS

Our results uncovered that TOM40 is a reliable prognostic marker and therapeutic target in OSCC.

Multicenter, retrospective GUIDANCE001 study comparing transarterial chemoembolization with or without tyrosine kinase and immune checkpoint inhibitors as conversion therapy to treat unresectable hepatocellular carcinoma: Survival benefit in intermediate or advanced, but not early, stages

BACKGROUND AND AIMS

Various conversion therapy options have become available to patients with unresectable HCC, but which conversion therapy is optimal for which type of patient is controversial. This study compared the efficacy and safety of TACE alone or combined with immune checkpoint and tyrosine kinase inhibitors.

APPROACH AND RESULTS

Data were retrospectively compared for patients with initially unresectable HCC who underwent conversion therapy consisting of TACE alone (n=459) or combined with immune checkpoint and tyrosine kinase inhibitors (n=343). Compared to the group that received TACE alone, the group that received triple conversion therapy showed significantly higher rates of overall survival (HR 0.43, 95%CI 0.35-0.53). In addition, triple therapy was associated with significantly longer median progression-free survival (15.9 vs. 8.0 mo, p <0.001). These results were confirmed in matched subsets of patients from each group. However, subgroup analysis confirmed the results only for patients with HCC in intermediate or advanced stages, not in an early stage. Those who received triple conversion therapy had a significantly higher rate of hepatectomy after conversion therapy (36.4 vs. 23.5%, p <0.001). Among those who underwent hepatectomy after conversion therapy, triple therapy was associated with a significantly higher rate of complete tumor response (32.1 vs. 11.1%, p <0.001). However, it was also associated with a significantly higher frequency of serious adverse events (35.6 vs. 27.0%, p =0.009).

CONCLUSIONS

Combining TACE with immune checkpoint and tyrosine kinase inhibitors was associated with significantly better survival and conversion efficacy than TACE alone among patients with intermediate or advanced unresectable HCC.

Transarterial chemoembolization combined with lenvatinib and sintilimab vs lenvatinib alone in intermediate-advanced hepatocellular carcinoma

BACKGROUND

Hepatocellular carcinoma (HCC) is the most common form of liver cancer that has limited treatment options and a poor prognosis. Transarterial chemoembolization (TACE) is the first-line treatment for intermediate-stage HCC but can induce tumour hypoxia, thereby promoting angiogenesis. Recent studies suggested that combining TACE with anti-angiogenic therapies and immunotherapy might improve efficacy. Lenvatinib, a tyrosine kinase inhibitor, has demonstrated superior outcomes compared to sorafenib, while immune checkpoint inhibitors such as sintilimab show potential when combined with TACE. However, the efficacy and safety of TACE combined with lenvatinib and sintilimab (TACE + SL) compared to TACE with lenvatinib alone (TACE + L) in patients with intermediate-advanced HCC has not yet been investigated.

AIM

To evaluate the efficacy and safety of TACE + SL therapy in comparison to TACE + L therapy in patients with intermediate-advanced HCC.

METHODS

A retrospective analysis was performed on patients with intermediate-advanced HCC who received TACE plus lenvatinib with or without sintilimab between September 2019 and September 2022. Baseline characteristics were compared, and propensity score matching was applied. Overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) were evaluated between the two groups, and adverse events were analyzed.

RESULTS

The study included 57 patients, with 30 in the TACE + SL group and 27 in the TACE + L group. The TACE + SL group demonstrated significantly improved median PFS and OS compared to the TACE + L group (PFS: 14.1 months vs 9.6 months, P = 0.016; OS: 22.4 months vs 14.1 months, P = 0.039), along with a higher ORR (70.0% vs 55.6%). After propensity score matching, 30 patients were included, with the TACE + SL group again showing longer median PFS and a trend toward improved OS (PFS: 14.6 months vs 9.2 months, P = 0.012; OS: 23.9 months vs 16.3 months, P = 0.063), and a higher ORR (73.3% vs 53.3%). No severe adverse events were reported.

CONCLUSION

TACE + SL demonstrated superior outcomes in terms of OS and PFS, compared to TACE + L. These findings suggest that the addition of sintilimab might enhance the therapeutic response in patients with intermediate-advanced HCC.

Chinese expert consensus on sequential surgery following conversion therapy based on combination of immune checkpoint inhibitors and antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2024 edition)

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits. In order to improve the long-term survival rate of the overall population with liver cancer and achieve the goal of a 15% increase in the overall 5-year survival rate outlined in the Healthy China 2030 blueprint, the Professional Committee for Prevention and Control of Hepatobiliary and Pancreatic Diseases of Chinese Preventive Medicine Association, Chinese Society of Liver Cancer, and the Liver Study Group of Surgery Committee of Beijing Medical Association organized in-depth discussions among relevant domestic experts in the field. These discussions focused on the latest progress since the release of the Chinese expert consensus on conversion therapy of immune checkpoint inhibitors combined antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2021 Edition) and resulted in a new consensus on the modifications and supplements to related key points. This consensus aims to further guide clinical practice, standardize medical care, and promote the development of the discipline.

Fully Covered Stent-TIPS for Advanced HCC Patients with Portal Vein Tumor Thrombus-Related Severe Symptomatic Portal Hypertension

Purpose

Portal vein tumor thrombus (PVTT)-related severe symptomatic portal hypertension (SPH) leads to a poor prognosis in patients with advanced hepatocellular carcinoma (HCC). Traditional transjugular intrahepatic portosystemic shunt (TIPS) using covered plus bare stent can effectively relieve SPH, however, the bare segment is susceptible to obstruction due to PVTT invasion. This study aimed to evaluate the safety and efficacy of fully covered stent-TIPS (FCS-TIPS) for treatment of PVTT-related SPH in advanced HCC patients.

Patients and Methods

This retrospective study enrolled 25 patients with advanced HCC who underwent FCS-TIPS for PVTT-related severe SPH from June 2018 to January 2024. The evaluated outcomes included overall survival (OS), technical success rate, reduction in portal venous pressure gradient (PPG), stent patency rate, SPH control rate, liver function and complications.

Results

The technical success rate was 100% without perioperative deaths or severe procedure-related adverse events. The average PPG decreased by 13.4±4.6 mmHg. The overall symptom control rate of SPH was 96.0%. Variceal bleeding, ascites/hydrothorax, and enteropathy control rates were 100%, 95.0%, and 100%, respectively. Liver function showed mild improvement one month after TIPS. One patient (4.0%) experienced overt hepatic encephalopathy (OHE) and three (12.0%) patients developed shunt dysfunction during the follow-up period. None of the patients experienced shunt-induced extrahepatic metastasis. The median OS was 6.0 months and the cumulative survival rates at 3, 6, 12 months were 80.0%, 52.0% and 21.3%.

Conclusion

FCS-TIPS is safe and effective for treating PVTT-related severe SPH and can serve as a bridging therapy for advanced HCC.

mFOLFOX-HAIC+lenvatinib+PD-1 inhibitors versus GC/GS/GEMOX chemotherapy as a first line therapy for advanced biliary tract cancer: A single-center retrospective cohort study

Biliary tract tumors (BTC) account for about 3% of all digestive system tumors, with rising incidence and limited treatment options, particularly for advanced stages, underscoring the need for innovative therapies. This retrospective cohort study evaluated the safety and efficacy of a novel regimen combining hepatic artery infusion chemotherapy with 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX-HAIC) alongside lenvatinib and programmed cell death protein-1 (PD-1) inhibitors (mFOLFOX-HAIC+lenvatinib+PD-1i) compared to standard regimens of gemcitabine plus cisplatin, gemcitabine plus S1, or gemcitabine plus oxaliplatin (GC/GS/GEMOX) in advanced BTC patients treated from March 2019 to November 2023. A total of 89 patients were analyzed, with 55 receiving hepatic arterial infusion chemotherapy and 34 receiving the GC/GS/GEMOX regimens. Among these, 23 patients were in the mFOLFOX-HAIC+lenvatinib+PD-1i group, while 24 were in the GC/GS/GEMOX group. The median progression-free survival (mPFS) for the mFOLFOX-HAIC+lenvatinib+PD-1i group was 15 months compared to 6 months for the GC/GS/GEMOX group. Similarly, the median overall survival (mOS) was 20 months for the mFOLFOXHAIC+lenvatinib+PD-1i group versus 13 months for the GC/GS/GEMOX group. The objective response rate (ORR) and disease control rate (DCR) for the mFOLFOX-HAIC+lenvatinib+PD-1i group were 48.5% and 87.0%, respectively, both significantly higher than those observed in the GC/GS/GEMOX group at three months of treatment. The incidence of adverse events (AEs) was similar between the mFOLFOX-HAIC+lenvatinib+PD-1i group and the GC/GS/GEMOX group, at 86.5% and 84.2%, respectively, with no statistically significant difference in complication rates. Overall, mFOLFOX-HAIC+lenvatinib+PD-1i appears to be a safe and well-tolerated treatment for advanced BTC, demonstrating superior mPFS and mOS compared to standard regimens.

Hepatic arterial infusion chemotherapy combined with immune checkpoint inhibitors and molecular targeted therapies for advanced infiltrative hepatocellular carcinoma: a single-center experience

Background

Infiltrative hepatocellular carcinoma (HCC) remains a therapeutic challenge due to its aggressive course and poor prognosis. Hepatic arterial infusion chemotherapy (HAIC) plus immune checkpoint inhibitors (ICIs) and molecular targeted therapies (MTTs) has shown early promise for advanced HCC, but its role in advanced infiltrative HCC is unclear. This study aims to investigate the efficacy and safety of HAIC combined with ICIs and MTTs in the treatment of advanced infiltrative HCC.

Methods

Patients with infiltrative HCC initially treated with HAIC plus ICIs and MTTs were consecutively included at our institution from November 2021 to June 2023. The efficacy evaluation included tumor response, time to response (TTR), duration of response (DOR), progression-free survival (PFS) per RECIST 1.1, and patient survival. Adverse events (AEs) were recorded for safety evaluation.

Results

A total of 27 patients were included and the median follow-up was 15.8 months (range, 4.3-25.9). The best objective response rate (ORR) and disease control rate (DCR) were 70.4% and 88.9%, respectively. The median TTR was 2.8 months (95% confidence interval [CI], 2.6-3.0) and the median DOR was 7.9 months (95% CI, 3.2-12.5). The median PFS was 7.5 months (95% CI, 4.2-10.7), and the median overall survival (OS) was 16.8 months (95% CI, 14.0-19.6), with a 1-year OS rate of 74.1%. No cases of grade 4 or 5 treatment-related adverse events (TRAEs) were observed in this study. Grade 3 TRAEs occurred in 17/27 (63.0%) patients, and the predominant grade 3 treatment-related adverse events were lymphocyte count decreased (18.5%) and neutrophil count decreased (14.8%).

Conclusions

The combination of HAIC plus ICIs and MTTs demonstrated encouraging outcomes and manageable safety concerns for infiltrative HCC.

Identification of prognostic tumor microenvironment in patients with advanced hepatocellular carcinoma treated with hepatic arterial infusion chemotherapy combined with lenvatinib and PD-1 inhibitors

BACKGROUND

In advanced hepatocellular carcinoma (HCC), the triple combination therapy of hepatic arterial infusion chemotherapy (HAIC) with lenvatinib and programmed cell death protein-1 (PD-1) inhibitors has shown promise as a front-line treatment. This study aimed to explore the tumor microenvironment (TME) characteristics of the population benefiting most from this treatment.

METHODS

The study included 44 patients, with 38 ultimately receiving the HAIC + FOLFOX + lenvatinib + PD-1 inhibitor treatment. Tumor response was evaluated using modified RECIST criteria, classifying patients as responders (complete or partial response) or non-responders (stable or progressive disease). Overall survival (OS), progression-free survival (PFS), and adverse events (AEs) were assessed. Additionally, genetic sequencing and RNA analysis were conducted on biopsy samples to identify TME differences between the two groups.

RESULTS

Among the 38 patients, 22 responded favorably, showing significantly longer median OS (not-reached vs. 8.6 months) and median PFS (15.3 months vs. 2.0 months) compared to non-responders. Common AEs included AST elevation, stomachache, nausea, and hypertension, with limited severe AEs. Genetic analysis revealed no significant differences in DNA features between the groups. However, RNA analysis indicated that responders had a more robust immune status, better drug sensitivity, and increased immune cell infiltration. Notably, higher levels of tumor-infiltrating T lymphocytes were linked to better responses, longer PFS, and OS.

CONCLUSION

The differences in the initial TME of patients, especially in tumor-infiltrating T lymphocytes, may be potential biomarkers for predicting response and prognosis. This finding provides clues to search for biomarkers for this triple combination therapy in advanced HCC.

The Prognostic Value of CRP/Alb Ratio in Predicting Overall Survival for Hepatocellular Carcinoma Treated with Transcatheter Intra-Arterial Therapy Combined with Molecular-Targeted Agents and PD-1/PD-L1 Inhibitors

Purpose

This study aimed to evaluate the prognostic value of C-reactive protein to albumin (CRP/Alb) ratio in hepatocellular carcinoma (HCC) treated with transcatheter intra-arterial therapy combined with molecular targeted agents (MTAs) and programmed cell death protein 1 (PD-1)/programmed death-ligand 1 (PD-L1) inhibitors.

Methods

Medical records of 271 consecutive patients with HCC receiving this combination therapy in China between 2019 and 2023 were retrospectively analyzed. Prognostic factors for progression-free survival (PFS) and overall survival (OS) were identified using univariate and multivariate Cox regression analyses. The discriminatory capability of inflammation-based prognostic scores-including the CRP/Alb ratio, C-reactive protein and alpha-fetoprotein in immunotherapy (CRAFITY) score, modified Glasgow prognostic score (mGPS), platelet-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII)-was assessed using the area under the curve (AUC).

Results

A total of 133 patients met the inclusion criteria. The optimal cutoff value for the binary classification of CRP/Alb ratio in predicting OS, as determined using X-tile software, was 0.02. Multivariate analysis identified the CRP/Alb ratio (hazard ratio [HR] = 2.61, p < 0.001), tumor size (HR = 2.45, p = 0.018), and extrahepatic metastases (HR = 1.93, p = 0.015) as independent predictors of OS. For PFS, significant factors included Eastern Cooperative Oncology Group Performance Status (HR = 1.55, p = 0.033) and macrovascular invasion (HR = 1.48, p = 0.046). Patients with higher CRP/Alb ratios were more likely to experience fever and fatigue. The CRP/Alb ratio demonstrated significantly higher AUCs than PLR and SII at 24 months (all p < 0.05) and showed comparable AUCs to CRAFITY score and mGPS at 12, 24, and 36 months.

Conclusion

The CRP/Alb ratio is a valuable prognostic marker for predicting OS and treatment-related adverse events in HCC patients receiving transcatheter intra-arterial therapy combined with MTAs and PD-1/PD-L1 inhibitors. This ratio can be used as a simple and reliable biomarker for assessing prognosis and guiding patient selection in clinical practice.

Salidroside enhances 5-fluorouracil sensitivity against hepatocellular carcinoma via YIPF5-induced mitophagy

Hepatocellular carcinoma (HCC) is a major medical challenge due to its high incidence and poor prognosis. 5-Fluorouracil (5-FU), although extensively studied in the treatment of HCC and other solid tumors, has limited application as a first-line therapy for HCC due to its resistance and significant inter-patient variability. To address these issues, researchers have explored drug repurposing. One of our key findings in this endeavour was the potent anti-HCC effect of the natural product Salidroside (Sal) when co-administered with 5-FU. Sal was found to inhibit mitosis and promote cellular senescence in HCC cells via a mechanism distinct from 5-FU, specifically by inducing excessive mitophagy that led to cellular mitochondrial dysfunction. Importantly, YIPF5 was confirmed as a potential molecular target of Sal. This natural product modulated YIPF5-induced mitophagy and influenced both mitosis and senescence in HCC cells. The combination of Sal and 5-FU demonstrated significant therapeutic effects in a mouse HCC model. In conclusion, our study was not only in line with the innovative strategy of drug repurposing, but also important for drug design and natural product screening targeting the relevant pathways.

Phase 2 study of serplulimab with the bevacizumab biosimilar HLX04 in the first-line treatment of advanced hepatocellular carcinoma

INTRODUCTION

This study aimed to evaluate the safety and preliminary efficacy of serplulimab, a novel programmed death-1 inhibitor, with or without bevacizumab biosimilar HLX04 as first-line treatment in patients with advanced hepatocellular carcinoma.

METHODS

This open-label, multicenter phase 2 study (clinicaltrials.gov identifier NCT03973112) was conducted in China and consisted of four treatment groups: group A (serplulimab 3 mg/kg plus HLX04 5 mg/kg, subsequent-line), group B (serplulimab 3 mg/kg plus HLX04 10 mg/kg, subsequent-line), group C (serplulimab 3 mg/kg, subsequent-line) and group D (serplulimab 3 mg/kg plus HLX04 10 mg/kg, first-line). Group D was the only group in which participants received the study treatment in the first-line setting. The primary endpoint was safety.

RESULTS

Following previous report on groups A and B, results of group D are herein presented. As of February 7, 2023, 61 patients were enrolled and were followed up for a median of 25.5 months. Grade ≥ 3 treatment-emergent adverse events were reported by 29 (47.5%) patients. One patient died from adverse events that were considered related to study treatment. Among the patients with at least one post-baseline tumor assessment (n = 58), the objective response rate was 29.3% (95% CI: 18.1-42.7) as assessed by an independent radiological review committee (IRRC) per RECIST v1.1. IRRC-assessed median progression-free survival was 7.3 months (95% CI: 2.8-11.0), and median overall survival was 20.4 months (95% CI: 15.0-NE), respectively.

CONCLUSION

Serplulimab combination therapy with HLX04 showed a manageable safety profile as well as preliminary efficacy in patients with advanced HCC in the first-line setting.

Metastasis-directed ablation of hepatocellular carcinoma with pulmonary oligometastases: a long-term multicenter study

PURPOSE

Ablation is a promising approach for eliminating intrathoracic metastases. We compared the effectiveness of a combination of metastasis-directed ablation and systemic therapy with that of systemic therapy alone for patients with hepatocellular carcinoma (HCC) having pulmonary oligometastases.

MATERIALS AND METHODS

We analyzed 679 patients with HCC and pulmonary oligometastases from seven tertiary hospitals. A total of 372 patients received systemic therapy (System group), whereas 307 patients received the combination therapy of pulmonary oligometastases ablation and systemic therapy (Ablation + System group).

RESULTS

The median progression-free survival (PFS) was 9.7 ± 0.6 and 11.5 ± 0.6 months in the System and Ablation + System groups, respectively. The Ablation + System group exhibited significantly better PFS (hazard ratio [HR], 0.71; 95% confidence interval [CI] 0.60-0.85; P < 0.001) and overall survival (OS) (HR, 0.65; 95% CI 0.52-0.81; P < 0.001) than the System group. The subgroup analysis revealed that OS (HR, 0.91; 95% CI 0.65-1.28; P = 0.590) and PFS (HR, 0.81; 95% CI 0.62-1.05; P = 0.100) did not differ between tyrosine kinase inhibitor (TKI) and TKI plus programmed cell death protein-1 (PD-1) inhibitor therapies in the Ablation + system group. In addition, PFS (HR, 0.53; 95% CI 0.38-0.74; P < 0.001) and OS (HR, 0.66; 95% CI 52-0.84; P < 0.001) showed obviously different for intrahepatic tumors with partial response (PR) status.

CONCLUSION

The application of a combination of ablation of pulmonary oligometastases and systemic therapy resulted in longer PFS and OS than systemic therapy alone.

Radiation-emitting metallic stent for unresectable Bismuth type III or IV perihilar cholangiocarcinoma: a multicenter randomized trial

BACKGROUND AND AIMS

Self-expandable metallic stents (SEMSs) have been recommended for patients with unresectable malignant biliary obstruction, while radiation-emitting metallic stents (REMSs) loaded with 125 I seeds have recently been approved to provide longer patency and overall survival in malignant biliary tract obstruction. This trial is to evaluate the efficacy and safety of REMS plus hepatic arterial infusion chemotherapy (REMS-HAIC) versus SEMS plus HAIC (SEMS-HAIC) for unresectable perihilar cholangiocarcinoma (pCCA).

MATERIALS AND METHODS

This multicenter randomized controlled trial recruited patients with unresectable Bismuth type III or IV pCCA between March 2021 and January 2023. Patients were randomly assigned (1:1 ratio) to receive either REMS-HAIC or SEMS-HAIC using permuted block randomization, with a block size of six. The primary endpoint was overall survival (OS). The secondary endpoints were time to symptomatic progression (TTSP), stent patency, relief of jaundice, quality of life, and safety.

RESULTS

A total of 126 patients were included in the intent-to-treat population, with 63 in each group. The median OS was 10.2 months versus 6.7 months ( P =0.002). The median TTSP was 8.6 months versus 5.4 months ( P =0.003). The median stent patency was longer in the REMS-HAIC group than in the SEMS-HAIC group ( P =0.001). The REMS-HAIC group showed better improvement in physical functioning scale ( P <0.05) and fatigue symptoms ( P <0.05) when compared to the SEMS-HAIC group. No significant differences were observed in relief of jaundice (85.7% vs. 84.1%; P =0.803) or the incidence of grade 3 or 4 adverse events (9.8% vs. 11.9%; P =0.721).

CONCLUSION

REMS plus HAIC showed better OS, TTSP, and stent patency compared with SEMS plus HAIC in patients with unresectable Bismuth type III or IV pCCA with an acceptable safety profile.

Comparison of the Long-term Survival Outcome of Surgery versus Stereotactic Body Radiation Therapy as Initial Local Treatment for Pulmonary Oligometastases from Colorectal Cancer: A Propensity Score Analysis

PURPOSE

Optimal local treatment for pulmonary oligometastases from colorectal cancer (CRC) remains unclear. We aimed to compare the long-term survival outcomes between surgery and stereotactic body radiation therapy (SBRT) as the initial local treatment for CRC pulmonary oligometastases.

MATERIALS AND METHODS

We retrospectively reviewed 335 consecutive patients who initially underwent surgery or SBRT for CRC pulmonary metastases from 2011 to 2022, and 251 patients (173 surgery and 78 SBRT) were ultimately included. Freedom from intrathoracic progression (FFIP), progression-free survival (PFS), and overall survival (OS) were compared using stabilized inverse probability of treatment weighting (sIPTW) analysis. In addition, patterns of intrathoracic progression and subsequent treatment were analyzed.

RESULTS

Median follow-up was 61.6 months for surgery and 54.4 months for SBRT. After sIPTW adjustment, significant differences emerged in both FFIP and PFS between surgery and SBRT (FFIP: hazard ratio [HR] = 0.50, 95% confidence interval [CI], 0.31-0.79; PFS: HR = 0.56, 95% CI, 0.36-0.87). The 3- and 5-year FFIP rates were 58.6% and 54.8%, respectively, after surgery, and 34.6% and 31.3%, respectively, after SBRT (P = .006). The 3- and 5-year PFS rates were 49.4% and 45.2%, respectively, after surgery, and 28.8% and 26.1%, respectively, after SBRT (P = .010). However, OS was not significantly affected by treatment approach (HR = 0.93, 95% CI, 0.49-1.76). The 3- and 5-year OS rates were 85.9% and 73.1%, respectively, after surgery, and 78.9% and 68.7%, respectively, after SBRT (P = .849). Recurrence at the treated site was more prevalent after SBRT than after surgery (33.3% vs 16.9%), whereas new intrathoracic tumors occurred more frequently after surgery than after SBRT (71.8% vs 43.1%). Both groups chose radiation therapy as the primary local salvage treatment.

CONCLUSIONS

Notwithstanding the significant differences in FFIP and PFS between surgery and SBRT, the long-term survival of patients with CRC pulmonary oligometastases did not depend on the initial choice of the local treatment approach.

Hepatic arterial chemotherapy infusion combined with tyrosine kinase inhibitors and PD-1 inhibitors for advanced hepatocellular carcinoma with high risk: a propensity score matching study

OBJECTIVE

To ascertain the therapeutic efficacy and safety of FOLFOX (oxaliplatin, fluorouracil, and leucovorin)-based hepatic arterial infusion chemotherapy combined with tyrosine kinase inhibitors (TKI) and programmed cell death protein-1 inhibitors (PD-1 inhibitors) (triple therapy), as a first-line treatment in high-risk advanced hepatocellular carcinoma (aHCC with Vp4 portal vein invasion or/and tumor diameter ≥10 cm).

METHODS

This retrospective multicenter study included 466 high-risk aHCC patients treated with either triple therapy ( n =245) or dual therapy (TKI and PD-1 inhibitors, n =221). The overall survival, progression-free survival, objective response rate, and safety were compared between the two groups. Propensity score matching was performed to reduce bias between the two groups.

RESULTS

After propensity score matching (1:1), 194 patients in each group were analyzed. The triple-therapy group showed a longer median overall survival (24.6 vs. 11.9 months; HR=0.43, P <0.001) and a longer median progression-free survival (10.0 vs. 7.7 months; HR=0.68, P =0.002) than the dual-therapy group. The survival rates at 6, 12, and 24 months were 94.2, 71.0, and 50.8% for triple therapy and 75.9, 49.9, and 26.8% for dual therapy. The objective response rate in the triple-therapy group was significantly higher (57.7 vs. 28.9%, P <0.001). In the triple-therapy group, more patients converted to non-high-risk (68.0 vs. 36.6%, P <0.001) and received salvage liver resection or ablation after downstaging conversion (16.5% vs. 9.2%, P =0.033). The grade 3/4 adverse events were 59.2 and 47.4% in the triple-therapy group and dual-therapy group, respectively ( P =0.022).

CONCLUSION

FOLFOX-based hepatic arterial infusion chemotherapy plus TKI and PD-1 inhibitors significantly improve survival prognosis compared with TKI plus PD-1 inhibitors. This is a potential first-line treatment for high-risk aHCC, with a relatively controlled safety profile.

Surgical resection versus thermal ablation: comparison of sequential options after successful TACE downstaging therapy for unresectable hepatocellular carcinoma

Background

Transarterial chemoembolization (TACE) is an effective and safe downstaging therapy for hepatocellular carcinoma (HCC). However, the selection of sequential therapeutic modalities is still controversial.

Objectives

This study compared the effectiveness and safety of surgical resection (SR) and thermal ablation (TA) after patients with HCC underwent TACE downstaging therapy.

Design

A retrospective, multi-institutional study.

Methods

From June 2008 to October 2022, a total of 4782 consecutive patients with HCC beyond the initial Milan criteria underwent TACE at 12 hospitals. Among them, 609 patients who received successful downstaging therapy were retrospectively reviewed. Among them, 209 patients underwent an SR, and 390 patients received TA after TACE. The propensity score matching (PSM) method was applied to reduce selection bias between groups. Cumulative overall survival (OS) and progression-free survival (PFS) were compared using the Kaplan-Meier method with the log-rank test.

Results

After PSM 1:1 (n = 185 in both groups), the cumulative 1-, 3-, 5-, and 10-year OS rates were 98.8%, 89.3%, 82.9%, and 64.4%, respectively, in the SR group and 99.5%, 88.4%, 75.3%, and 53.9%, respectively, in the TA group; these two groups were not significantly different (HR: 1.22; 95% CI: 0.78-1.89; p = 0.381). The cumulative 1-, 3-, 5-, and 10-year PFS rates were 88.5%, 69.2%, 58.8%, and 32.2%, respectively, in the SR group and 90.6%, 71.4%, 53.1%, and 32.0%, respectively, in the TA group, revealing no significant difference between the two groups (HR: 0.97; 95% CI: 0.71-1.32; p = 0.855).

Conclusion

For HCC patients beyond the Milan criteria who received TACE downstaging therapy, TA might be acceptable as an alternative to SR in the first-line sequential treatment scheme.

Optimal candidates and surrogate endpoints for HAIC versus Sorafenib in hepatocellular carcinoma: an updated systematic review and meta-analysis

BACKGROUND AND AIMS

Hepatic artery infusion chemotherapy (HAIC) has been a long-standing intervention for hepatocellular carcinoma (HCC). Despite positive clinical outcomes, its inclusion in guidelines remains limited due to a lack of evidence-based support. This study aims to identify optimal target populations for HAIC and validate associations between intermediate endpoints with overall survival (OS).

METHODS

Following PRISMA guidelines, a comprehensive search was conducted in PubMed, Embase, Cochrane Library, and Web of Science. The primary search strategy was based on medical subject headings terms (MeSH) using 'Hepatic arterial infusion chemotherapy', 'HAIC', 'Sorafenib', 'Nexavar', 'hepatocellular carcinoma', 'HCC', 'Liver cancer', combined with free text words. Data extraction, quality assessment, and analysis were performed according to preregistered protocol.

RESULTS

A total of 26 studies, 6456 HCC patients were included for analysis (HAIC, n =2648; Sorafenib, n =3808). Pooled outcomes revealed that Sorafenib demonstrated better OS only in patients who were refractory to trans-arterial chemoembolization (TACE) (HR=1.32, 95% CI [1.01-1.73]), in other subgroups or overall HCC population HAIC consistently outperformed Sorafenib in patients' survival. Radiologically, higher response rates in the HAIC group does not necessarily translate into survival improvement, but the hazard ratios (HRs) of 1-year-OS (R 2 =0.41, P =0.0044) and 1-year-progression free survival (1y-PFS) (R 2 =0.77, P =0.0002) strongly correlated with the patients OS. Meanwhile, larger tumour size (HR=1.86, 95% CI [1.12-3.1, 95%), heavier tumour burden (HR=2.32, 95% CI [1.33-4.02), existence of MVI or EHS (HR=1.65, 95% CI [1.36-2]; HR=1.60, 95% CI [1.19-2.14]), and AFP >400 ng/ml (HR=1.52, 95% CI [1.20-1.92]) were identified as independent risk factors for OS, while HAIC treatment (HR=0.54, 95% CI [0.35-0.82]) and lower BCLC stage (HR=0.44, 95% CI [0.28-0.69]) were potential protective factors for HCC patients.

CONCLUSION

HAIC monotherapy appears noninferior to Sorafenib in HCC treatment, with potential benefits in specific subgroups. The robust correlation between 1y-OS/1y-PFS and OS, alongside identified risk and protective factors from the present study, offers valuable insights for designing future large prospective studies in this field.

Screening and molecular mechanism research on bile microRNAs associated with chemotherapy efficacy in perihilar cholangiocarcinoma

The efficacy of hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin (OXA) and 5-fluorouracil (5-Fu) for treating advanced perihilar cholangiocarcinoma (pCCA) has been demonstrated, yet the survival benefits of HAIC for pCCA patients vary. Here, we aimed to screen out HAIC resistance-related bile microRNAs (miRNAs) and explore the functions of specific bile miRNAs in pCCA based on high-throughput sequencing. Levels of bile miR-532-3p, miR-1250-5p, and miR-4772-5p were related to the survival of advanced pCCA patients after HAIC. However, only overexpression of miR-532-3p promoted OXA/5-Fu resistance, and downregulation of its expression improved sensitivity to OXA/5-Fu. Mechanistic investigations revealed secreted protein acidic and rich in cysteine (SPARC) as the direct target of miR-532-3p. Our study reveals that bile miR-532-3p, miR-1250-5p, and miR-4772-5p may serve as survival biomarkers in advanced pCCA patients after HAIC and that bile miR-532-3p promotes resistance to HAIC with OXA and 5-Fu via negatively regulating SPARC expression.

Transarterial Chemoembolization Plus Camrelizumab and Rivoceranib versus Camrelizumab and Rivoceranib Alone for BCLC Stage C Hepatocellular Carcinoma

Purpose

Camrelizumab and rivoceranib together provide a new first-line treatment approach for unresectable hepatocellular carcinoma (HCC). Meanwhile, transarterial chemoembolization (TACE) is an effective method for the local control of the HCC. The study compared the clinical benefit and safety between TACE with camrelizumab-rivoceranib and camrelizumab-rivoceranib alone for Barcelona Clinic Liver Cancer (BCLC)-C HCC patients.

Patients and Methods

This multi-center retrospective analysis included continuous BCLC-C HCC patients who received camrelizumab-rivoceranib with TACE and camrelizumab-rivoceranib alone from January 2020 to December 2022. The therapeutic response, progression-free survival (PFS), safety, and overall survival (OS) were compared. The quantitative data were compared via the t-test or Mann-Whitney U-test. Comparison of the categorical data was done by chi-square or Fisher's exact tests. The comparison of PFS with OS was compared by Log rank test. A Multivariate Cox regression test was utilized to identify risk variables for both PFS and OS.

Results

 This analysis comprised 132 BCLC-C HCC patients who received camrelizumab-rivoceranib alone (n = 74) or combined treatment (n = 58). The combined group displayed higher partial response (44.8% vs 21.6%, p = 0.004) and total response (55.2% versus 36.5%, p = 0.032) rates than camrelizumab-rivoceranib alone group. The median PFS (13.5 months vs 10.3 months, p = 0.046) and OS (22.8 months vs 18.4 months, p = 0.041) for the combined group was significantly longer relative to the camrelizumab-rivoceranib alone group. Additional risk factors, excluding the therapy option, were a higher alpha-fetoprotein level and Eastern Cooperative Oncology Group performance status. The incident rates of camrelizumab-rivoceranib-related advents were comparable between combined and camrelizumab-rivoceranib alone groups (46.3% vs 51.4%, p = 0.572). The combined group contained 33 patients (56.9%) who experienced temporary post-embolization symptoms.

Conclusion

For BCLC-C HCC patients, TACE may significantly increase the therapeutic effectiveness of camrelizumab-rivoceranib without increasing the risk of camrelizumab-rivoceranib-related complications.

ALBI Grade Analyses of TACE Combined with Anti-Angiogenesis Therapies Plus PD-1 Inhibitors versus Anti-Angiogenesis Therapies Plus PD-1 Inhibitors in Advanced HCC

Objective

To evaluate the baseline albumin-bilirubin (ALBI) grade's role in advanced hepatocellular carcinoma (HCC) receiving transarterial chemoembolization (TACE) plus anti-angiogenesis therapies and PD-1 inhibitors (TACE+TP) versus anti-angiogenesis therapies and PD-1 inhibitors (TP).

Methods

This multicenter retrospective study enrolled advanced HCC undergoing TACE+TP or TP from January 2019 to June 2023 at three hospitals in China. The primary outcomes were time to progression of the ALBI grade and change in ALBI score between the initial baseline and the final assessment point available, the secondary outcomes consisted of overall survival (OS) as well as progression-free survival (PFS).

Results

One hundred and eighty-three patients were ultimately enrolled in this study for analysis, of whom 44 were categorized as having an ALBI grade 1 (TACE+TP, n = 23; TP, n = 21) and 139 were classified as ALBI grade 2 (n = 77; n = 62). Time to progression of the ALBI grade, indicating liver function deterioration, was comparable between the TACE+TP and TP groups (median, 11.2 vs 19.3 months; P = 0.353). Change in ALBI score between the initial baseline and the final assessment point available was comparable among the two groups (difference in least squares mean, 0.084). Irrespective of the initial ALBI grade, patients in TACE+TP group exhibited a significant enhancement in OS and displayed a promising trend towards better PFS.

Conclusion

TACE+TP had no negative influence on liver function and enhanced survival regardless of baseline ALBI grade when compared to TP in advanced HCC patients.

A real-world pharmacovigilance study of Sorafenib based on the FDA Adverse Event Reporting System

Aims

The primary objective of this study was to closely monitor and identify adverse events (AEs) associated with Sorafenib, a pharmacological therapeutic agent used to treat hepatocellular carcinoma, renal cell carcinoma, and thyroid cancer. The ultimate goal was to optimize patient safety and provide evidence-based guidance for the appropriate use of this drug.

Methods

Reports from the FDA Adverse Event Reporting System (FAERS) database were comprehensively collected and analyzed, covering the first quarter of 2004 to the first quarter of 2024. Disproportionality analysis was performed using robust algorithms for effective data mining to quantify the signals associated with Sorafenib-related AEs.

Results

In total, we identifued 18,624 patients (82,857 AEs in the Sorafenib population) from the collected reports and examined, the occurrence of Sorafenib-induced AEs in 26 organ systems. The study results revealed the presence of the expected AEs, including Diarrhoea, Palmar-plantar erythrodysaesthesia syndrome, Hepatocellular carcinoma, Fatigue, and Rash, which was consistent with the information provided in the drug insert. In addition, unexpected significant AEs, such as Gait inability, Palmoplantar keratoderma and Hyperkeratosis were observed at the preferred term (PT) level. These findings suggest the potential occurrence of adverse reactions not currently documented in drug descriptions.

Conclusion

This study successfully detected new and unforeseen signals associated with Sorafenib-related AEs related to Sorafenib administration, providing important insights into the complex correlations between AEs and Sorafenib use. The results of this study emphasize the critical importance of continuous and vigilant surveillance for the timely identification and effective management of AEs to improve the overall patient safety and wellbeing in the context of Sorafenib therapy.

Prognostic utility of gamma-glutamyl transpeptidase to platelet ratio in patients with solitary hepatitis B virus-related hepatocellular carcinoma after hepatectomy

BACKGROUND

The prognostic impact of preoperative gamma-glutamyl transpeptidase to platelet ratio (GPR) levels in patients with solitary hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) following radical resection has not been established.

AIM

To examine the clinical utility of GPR for prognosis prediction in solitary HBV-related HCC patients.

METHODS

A total of 1167 solitary HBV-related HCC patients were retrospectively analyzed. GPR levels were compared with 908 non-HCC individuals. Overall survival (OS) and recurrence-free survival (RFS) were evaluated, and cox proportional hazard model analyses were performed to identify independent risk factors. Differences in characteristics were adjusted by propensity score matching (PSM). Subgroup and stratified survival analyses for HCC risks were performed, and a linear trend of the hazard ratio (HR) according to GPR levels was constructed.

RESULTS

GPR levels of patients with solitary HBV-related HCC were higher than those with hepatic hemangiomas, chronic hepatitis B and healthy control (adjusted P < 0.05). Variable bias was diminished after the PSM balance test. The low GPR group had improved OS (P < 0.001) and RFS (P < 0.001) in the PSM analysis and when combined with other variables. Multivariate cox analyses suggested that low GPR levels were associated with a better OS (HR = 0.5, 95%CI: 0.36-0.7, P < 0.001) and RFS (HR = 0.57, 95%CI: 0.44-0.73, P < 0.001). This same trend was confirmed in subgroup analyses. Prognostic nomograms were constructed and the calibration curves showed that GPR had good survival prediction. Moreover, stratified survival analyses found that GPR > 0.6 was associated with a worse OS and higher recurrence rate (P for trend < 0.001).

CONCLUSION

Preoperative GPR can serve as a noninvasive indicator to predict the prognosis of patients with solitary HBV-related HCC.

Comprehensive treatment focusing on transarterial chemoembolization for postoperative liver metastasis in gastric cancer patients

OBJECTIVE

To investigate the clinical efficacy of comprehensive treatment focusing on transarterial chemoembolization (TACE) for postoperative liver metastasis in patients with gastric cancer and analyze the factors influencing prognosis.

METHODS

A retrospective study was conducted on 116 patients who developed liver metastasis after gastric cancer surgery and were admitted to Gansu Provincial Cancer Hospital between January 2018 and February 2020. The observation group, consisting of 62 patients, received TACE with fluorouracil (FU) + irinotecan (CPT-11) + oxaliplatin (OXA) and moderate lipiodol embolization. The control group, consisting of 54 patients, received systemic S-1 and Oxaliplatin regimen (SOX) alone. The clinical efficacy and incidence of adverse reactions were compared between the two groups. Liver function indicators, tumor markers, and immunoglobulin changes were analyzed in both groups. The 2-year survival rate of patients was analyzed using the Kaplan-Meier (K-M) curve. Lasso-Cox regression was used to identify independent prognostic factors affecting the 2-year survival rate. A Nomogram model was constructed to predict outcomes.

RESULTS

The overall clinical efficacy (P = 0.001) and objective response rate (ORR) (P = 0.001) were significantly lower in the control group compared to the observation group. No significant differences were found in ALT and AST changes between the two groups (P > 0.05). Post-treatment, CEA and CA19-9 levels were significantly lower, and IgG and IgM levels were significantly higher in the observation group (P < 0.001). There was no significant difference in the incidence of adverse reactions (P > 0.05). Lasso-Cox regression identified treatment plan, pathological differentiation, degree of liver metastasis, and pre-treatment CEA as independent prognostic factors for 2-year survival. Based on these, a Nomogram model was constructed. In the training group, the model had AUC values over 0.8 for 1- and 2-year survival rates, and in the validation group, the AUC was 0.765 and 0.687, respectively, indicating good predictive performance.

CONCLUSION

Compared to the conventional SOX regimen, comprehensive treatment focusing on TACE embolization for postoperative liver metastasis in gastric cancer is more effective and can improve survival rates.

Hepatic arterial infusion chemotherapy plus regorafenib compared with regorafenib alone as second-line therapy for advanced hepatocellular carcinoma: a randomised controlled trial protocol

INTRODUCTION

The exact role of hepatic arterial infusion chemotherapy (HAIC) in advanced hepatocellular carcinoma (aHCC) is still unknown. The combination of HAIC and sorafenib has been proven to be more effective than sorafenib alone in the first-line treatment of aHCC. The aim of the study is to evaluate the efficacy and safety of HAIC plus regorafenib in the second-line treatment of aHCC.

METHODS AND ANALYSIS

This is a multicenter, open-label, randomised controlled phase III trial. A total of 294 patients with aHCC, who are unable to tolerate the first-line systemic therapy or progress after the first-line systemic therapy, will be enrolled in the study. The patients will be randomly (2:1) assigned into the combination treatment group (HAIC plus regorafenib, n=196) and the control group (regorafenib alone, n=98). HAIC and regorafenib (160 mg/day) will be given in a 4-week cycle. The primary endpoint is overall survival in the intention-to-treat population. The second endpoints include progression-free survival, overall response rate, time to progression, etc. The radiological assessments will be based on the criteria of Response Evaluation Criteria in Solid Tumors 1.1.

ETHICS AND DISSEMINATION

This study is approved by the ethics committee of Cancer Hospital, Chinese Academy of Medical Sciences. All participants are required to provide written informed consent. The results of this study will be disseminated through peer-reviewed publications and esteemed academic conferences.

APASL clinical practice guidelines on systemic therapy for hepatocellular carcinoma-2024

In Asia-Pacific region, hepatocellular carcinoma is a serious health threat attributing to over 600,000 deaths each year and account for over 70% of global cases. Clinically, the major unmet needs are recurrence after curative-intent surgery, liver transplantation or local ablation and disease progression in those with hepatocellular carcinoma not eligible for resection or failed locoregional therapy. In the recent few years, new targeted therapy and immune-checkpoint inhibitors have been registered as systemic therapy to address these issues. Notably, new forms of systemic therapy, either as first-line or second-line therapy for unresectable hepatocellular or those not eligible for locoregional therapy, are now available. New data is also emerging with the use of systemic therapy to prevent hepatocellular carcinoma recurrence after curative-intent resection or local ablation therapy and to retard disease progression after locoregional therapy. In the future, further implementation of immune-checkpoint inhibitors and other forms of immunotherapy are expected to bring a new paradigm to the management of hepatocellular carcinoma. New insight related to immune-related adverse events with the use of immunotherapy has allso enabled optimization of the therapeutic approach to patients with hepatocellular carcinoma. The purpose of this clinical practice guideline is to provide an up-to-date recommendation based on clinical evidence and experience from expert Asia-Pacific key opinion leaders in the field of hepatocellular carcinoma. Three key questions will be addressed, namely: (1) Which patients with hepatocellular carcinoma should be considered for systemic therapy? (2) Which systemic therapy should be used? (3) How should a patient planned for immune checkpoint-based systemic therapy be managed and monitored?

Stereotactic Body Radiotherapy Combined With Lenvatinib With or Without PD-1 Inhibitors as Initial Treatment for Unresectable Hepatocellular Carcinoma

PURPOSE

The aim of this study was to compare the clinical benefit and safety of the triple combination of stereotactic body radiotherapy (SBRT), lenvatinib, and programmed cell death protein 1 (PD-1) inhibitors with the dual combination of SBRT and lenvatinib in patients with unresectable hepatocellular carcinoma (uHCC).

METHODS AND MATERIALS

Patients with uHCC who received SBRT in combination with lenvatinib and PD-1 inhibitors or SBRT in combination with lenvatinib alone as first-line treatment from October 2018 to July 2022 were reviewed in this study. The primary endpoints were overall survival (OS) and progression-free survival (PFS). The secondary endpoints were intrahepatic PFS, extrahepatic PFS, and objective remission rate. In addition, safety profiles were assessed by analyzing treatment-related adverse events between the two groups to assess safety profiles.

RESULTS

In total, 214 patients with uHCC who received combination therapy were included in this retrospective study. Among them, 146 patients received triple combination therapy of SBRT, lenvatinib, and PD-1 inhibitors (SBRT-L-P group), and 68 patients received dual therapy of SBRT and lenvatinib (SBRT-L group). The median OS times of the 2 groups were 31.2 months and 17.4 months, respectively (P < .001). The median PFS time was significantly longer in the SBRT-L-P group than in the SBRT-L group (15.6 months vs 8.8 months, P < .001). Additionally, the median intrahepatic PFS (17.5 vs 9.9 months, P < .001) and extrahepatic PFS (20.9 vs 11.6 months, P < .001) were significantly longer in the SBRT-L-P group than in the SBRT-L group. The objective remission rate in the SBRT-L-P group was higher than in the SBRT-L group (63.0 vs 39.7%, P = .002). The incidence and severity of treatment-related adverse events in the SBRT-L-P group were comparable to those in the SBRT-L group.

CONCLUSION

The use of both lenvatinib and PD-1 inhibitors with SBRT in patients with uHCC was associated with improved overall survival compared with lenvatinib and SBRT alone with a manageable safety profile.

Longitudinal Body Composition Identifies Hepatocellular Carcinoma With Cachexia Following Combined Immunotherapy and Target Therapy (CHANCE2213)

BACKGROUND

Cancer cachexia can impact prognosis, cause resistance to anticancer treatments and affect the tolerability of treatments. This study aims to identify hepatocellular carcinoma (HCC) with cachexia by characterizing longitudinal body composition (BC) trajectories.

METHODS

This longitudinal, multicentre cohort study included unresectable HCC patients treated with first-line programmed death-(ligand)1 inhibitors plus anti-vascular endothelial growth factor antibody/tyrosine kinase inhibitors between 01/2018-12/2022. BC measurements including skeletal muscle mass (SMM) and total adipose tissue area (TATA) were evaluated by computed tomography at the third lumbar vertebra at baseline and follow-up imaging. Unsupervised latent class growth mixed models were applied to distinguish potential longitudinal SMM and TATA trajectories for identifying cachexia. The primary study endpoint was overall survival (OS), with secondary endpoints including progression-free survival (PFS), objective response rate (ORR) and safety. Multiple Cox proportional hazards models were used to calculate adjusted hazard ratios (HRs) for survival.

RESULTS

A total of 411 patients with 2138 time-point measurements were included. The median age was 56 years, and 50 (12.2%) patients were female. Two distinct trajectories were identified for SMM and TATA: sharp-falling and stable. SMM sharply declined in 58 patients (14.1%) and TATA in 71 of 406 patients (17.5%) with significant worse OS (for SMM, 17.0 vs. 24.9 months; p < 0.001; HR = 0.59; for TATA, 15.3 vs. 25.1 months; p < 0.001; HR = 0.44). Patients were categorized into three phases based on trajectories: pre-cachexia (SMM and TATA stable, n = 299, 73.6%), cachexia (SMM or TATA sharp-falling, n = 86, 21.2%) and refractory cachexia (SMM and TATA sharp-falling, n = 21, 5.2%). Patients with refractory cachexia exhibited the worst OS, PFS and ORR, followed by those with cachexia. The median OS was 11.5 months for refractory cachexia, 17.7 for cachexia and 26.0 for pre-cachexia; median PFS was 6.0, 7.9 and 10.9 months, respectively, with ORR of 4.8%, 39.5% and 54.2%, respectively (all ps < 0.001). Multivariable Cox analysis identified refractory cachexia as an independent risk factor for both OS (HR = 3.31; p < 0.001) and PFS (HR = 2.94; p < 0.001), with cachexia also showing significant impacts. Grade 3-4 adverse events were higher in patients with refractory cachexia (23.8%) and cachexia (8.1%) compared with pre-cachexia (6.0%; p = 0.010).

CONCLUSIONS

HCC patients with cachexia and refractory cachexia were identified by longitudinal BC trajectories. Falling trajectories of BC identified refractory cachexia patients with worst response, survival and poor tolerability from systemic therapy combinations.

Lenvatinib plus drug-eluting bead transarterial chemoembolization with/without hepatic arterial infusion chemotherapy for hepatocellular carcinoma larger than 7 cm with major portal vein tumor thrombosis: a multicenter retrospective cohort study

BACKGROUND

The management of hepatocellular carcinoma (HCC) with high tumor burden and major portal vein tumor thrombosis (PVTT) remains a great challenge. The authors aimed to investigate the efficacy and safety of lenvatinib plus drug-eluting bead transarterial chemoembolization (DEB-TACE) and hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin, fluorouracil and leucovorin (Len+DEB-TACE+HAIC) versus lenvatinib plus DEB-TACE (Len+DEB-TACE) for HCC greater than 7.0 cm accompanied with major PVTT.

MATERIALS AND METHODS

This multicenter retrospective cohort study evaluated consecutive patients with HCC (> 7.0 cm) and major PVTT who received Len+DEB-TACE+HAIC (Len+DEB-TACE+HAIC group) or Len+DEB-TACE (Len+DEB-TACE group) between July 2019 and June 2021 from eight institutions in China. Objective response rate (ORR), time to progression (TTP), overall survival (OS), and treatment-related adverse events (TRAEs) were compared between the two groups by propensity score matching (PSM).

RESULTS

A total of 205 patients were included. After PSM, 85-paired patients remained in the study cohorts. Patients in the Len+DEB-TACE+HAIC group had higher ORR (61.2% vs. 34.1%, P < 0.001), longer TTP (median, 9.8 vs. 5.9 months, P < 0.001), and prolonged OS (median, 16.7 vs. 12.5 months, P < 0.001) than those in the Len+DEB-TACE group. The ORR and TTP of both intrahepatic tumor (ORR: 64.7% vs. 36.5%, P < 0.001; median TTP: 10.7 vs. 7.0 months, P < 0.001) and PVTT (ORR: 74.1% vs. 47.1%, P < 0.001; median TTP: 17.4 vs. 7.6 months, P < 0.001) were better in the Len+DEB-TACE+HAIC group than the Len+DEB-TACE group. The frequency of grade 3-4 TRAEs in the Len+DEB-TACE+HAIC group were comparable to those in the Len+DEB-TACE group (38.8% vs. 34.1%, P = 0.524).

CONCLUSION

The addition of HAIC to Len+DEB-TACE significantly improved ORR, TTP, and OS over Len+DEB-TACE with an acceptable safety profile for large HCC with major PVTT.

Development and validation of web-based risk score predicting prognostic nomograms for elderly patients with primary colorectal lymphoma: A population-based study

Background and Objectives

Primary colorectal lymphoma (PCL) is an infrequently occurring form of cancer, with the elderly population exhibiting an increasing prevalence of the disease. Furthermore, advanced age is associated with a poorer prognosis. Accurate prognostication is essential for the treatment of individuals diagnosed with PCL. However, no reliable predictive survival model exists for elderly patients with PCL. Therefore, this study aimed to develop an individualized survival prediction model for elderly patients with PCL and stratify its risk to aid in the treatment and monitoring of patients.

Methods

Patients aged 60 or older with PCL from 1975 to 2013 in the Surveillance, Epidemiology, and End Results database were selected and randomly divided into a training cohort (n = 1305) and a validation cohort (n = 588). The patients from 2014-2015 (n = 207) were used for external validation. The research team utilized both Cox regression and the least absolute shrinkage and selection operator (LASSO) regression to analyze potential predictors, in order to identify the most suitable model for constructing an OS-nomogram and an associated network version. The risk stratification is constructed on the basis of this model. The performance of the model was evaluated based on the consistency index (C-index), calibration curve, and decision curve analysis (DCA) to determine its resolving power and calibration capability.

Results

Age, gender, marital status, Ann Arbor staging, primary site, surgery, histological type, and chemotherapy were independent predictors of Overall Survival (OS) and were therefore included in our nomogram. The Area Under the Curve (AUC) of the 1, 3, and 5-year OS in the training, validation, and external validation sets ranged from 0.732 to 0.829. The Receiver Operating Characteristic (ROC) curves showed that the nomogram model outperformed the Ann Arbor stage system when predicting elderly patients with PCL prognosis at 1, 3, and 5 years in the training set, validation dataset, and external validation cohort. The Concordance Index (C-index) also demonstrated that the nomogram had excellent predictive accuracy and robustness. The calibration curves demonstrated a strong agreement between observed and predicted values. In the external validation cohort, the C-index (0.769, 95%CI: 0.712-0.826) and calibration curves of 1000 bootstrap samples also indicated a high level of concordance between observed and predicted values. The nomogram-related DCA curves exhibited superior clinical utility when compared to Ann Arbor stage. Furthermore, an online prediction tool for overall survival has been developed: https://medkuiwang.shinyapps.io/DynNomapp/.

Conclusion

This was the first study to construct and validate predictive survival nomograms for elderly patients with PCL, which is better than the Ann Arbor stage. It will help clinicians manage elderly patients with PCL more accurately.

Sequencing of systemic therapy in unresectable hepatocellular carcinoma: A systematic review and Bayesian network meta-analysis of randomized clinical trials

PURPOSE

For patients with advanced or unresectable hepatocellular carcinoma (HCC), safe and effective therapies are urgently needed to improve their long-term prognosis. Although the guidelines recommend first-line treatments such as sorafenib, lenvatinib, and atezolizumab in combination with bevacizumab (T+A) and second-line treatments such as regorafenib, the efficacy comparison between drugs is lacking, that is, a treatment is not recommended as the optimal or alternative choice for a specific patient population. Therefore, we will conduct a high-quality network meta-analysis based on Phase III randomized controlled trials (RCTs) to systematically evaluate and compare overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and serious adverse events (SAE) of different treatment protocols in the context of first-line and second-line therapies, which are critical for clinical decision making and prognostic improvement in advanced HCC patients.

METHODS

The studies of interest were Phase III RCTs evaluating the efficacy or safety of first- or second-line therapies in patients with unresectable or advanced HCC. Literature published in English from the four databases of PubMed, Embase, Cochrane Library, and Web of Science was comprehensively searched from the inception to May 23, 2022. Outcomes of interest included OS, PFS, ORR, and SAE. A league table was developed to show the results of the comparison between different treatments. A histogram of cumulative probability was drawn to discuss the ranking probability of treatments based on different outcomes. The effectiveness and safety of various treatments were comprehensively considered and the two-dimensional diagram was plotted to guide clinical practice. The Gemtc package in R Studio was used for network meta-analysis in a Bayesian framework.

RESULTS

The results showed that HAIC-FO was superior to T+A regimen, regardless of OS, PFS or ORR. TACE combined with lenvatinib performed better than T+A in PFS, and ORR. In addition to the T+A regimen, Sintilimab combined with IBI305 and camrelizumab combined with apatinib were also associated with longer OS, PFS, and ORR, and their SAE incidence was not higher than that of T+A, especially for camrelizumab combined with apatinib, its safety was better than that of T+A regimen. There were no new treatments or combinations that were more effective than regorafenib. It was important to note that for PFS, the efficacy of apatinib and cabozantinib was not statistically different from that of regorafenib, so these two treatments could be used as alternative treatment options in cases where regorafenib was not tolerated or treatment failed.

CONCLUSIONS

We conducted a network meta-analysis to evaluate the efficacy and safety of multiple treatment modalities by integrating the results of direct and indirect comparisons. This study included high-quality multicenter Phase III RCTs, collated and summarized all treatments involved in advanced or unresectable HCC in first-line and second-line settings, and compared with T+A and regorafenib, respectively, and ranked based on efficacy and safety to support clinical decision making.

Idarubicin-loaded degradable hydrogel for TACE therapy enhances anti-tumor immunity in hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is a common and deadly cancer, often diagnosed at advanced stages, limiting surgical options. Transcatheter arterial chemoembolization (TACE) is a primary treatment for inoperable and involves the use of drug-eluting microspheres to slowly release chemotherapy drugs. However, patient responses to TACE vary, with some experiencing tumor progression and recurrence. Traditional TACE uses agents like oil-based drug emulsions and polyvinyl alcohol particles, which can permanently block blood vessels and increase tumor hypoxia. Additionally, TACE can suppress the immune system by reducing immune cell numbers and function, contributing to poor treatment outcomes. New approaches, like TACE using degradable starch microspheres and hydrogel-based materials, offer the potential to create different tumor environments that could improve both safety and efficacy. In our research, we developed a composite hydrogel (IF@Gel) made of Poloxamer-407 gel and Fe3O4 nanoparticles, loaded with idarubicin, to use as an embolic material for TACE in a rat model of orthotopic HCC. We observed promising therapeutic effects and investigated the impact on the tumor immune microenvironment, focusing on the role of immunogenic cell death (ICD). The composite hydrogel demonstrated excellent potential as an embolic material for TACE, and IF@Gel-based TACE demonstrated significant efficacy in rat HCC. Furthermore, our findings highlight the potential synergistic effects of ICD with anti-PD-L1 therapy, providing new insights into HCC treatment strategies. This study aims to provide improved treatment options for HCC and to deepen our understanding of the mechanisms of TACE and tumor environment regulation.

Efficacy and safety of hepatic arterial infusion chemotherapy combined with donafenib in the treatment of unresectable hepatocellular carcinoma

OBJECTIVE

This study aimed at ascertaining the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) combined with donafenib versus HAIC alone in the treatment of unresectable hepatocellular carcinoma (HCC).

METHODS

Seventy HCC patients were enrolled for our study, and they were randomized by simple randomization using computer-generated random numbers into two groups: control group and observation group. Regular follow-up reviews were conducted to assess the efficacy of treatments. The levels of apoptotic factors, the levels of hepatic fibrosis indices, the levels of serum tumor vascular factors and tumor markers, and the occurrence of adverse reactions in the two groups were recorded and compared.

RESULTS

Disease control rate, objective response rate, and progression-free survival (PFS) of patients in the observation group were higher in contrast to the control group. After 12 weeks of treatment, lower mRNA expression of c-mesenchymal-epithelial transition factor, telomerase, and Fas Ligand and higher mRNA expression of Fas and Caspase-3 were observed in HCC tissues of the observation group versus the control group (p < 0.05); lower detection values of serum laminin, hyaluronic acid, collage type IV, vascular endothelial growth factor receptor 2, and alpha-fetal protein (AFP) were noted in HCC patients of the observation group in comparison to the control group (p < 0.05); there was no difference in the incidence of adverse reactions between the two groups.

CONCLUSION

Donafenib combined with HAIC in the treatment of unresectable HCC patients can notably reduce serum AFP levels, improve hepatic fibrosis, enhance short-term efficacy, prolong PFS, and have a favorable safety profile.

A total of 51 eligible patients were recruited. The objective response rate (ORR) based on mRECIST and RECIST 1.1 criteria were 60.8% and 45.1%, respectively. The surgical conversion rate was 25.5%. The median progression-free survival (PFS) was 15.2 months. The 1-year overall survival rate was 88.2%. Adverse events were observed in 98% patients, with 23.5% experiencing grade 3 or 4 adverse events.

Conclusion

The FOLFOX-HAIC combined with targeted immunotherapy regimen is effective in patients with unresectable HCC, demonstrated by a high surgical conversion rate and manageable adverse effects. This regimen represents a potential novel first-line treatment option for HCC.

Combinatorial treatment with traditional medicinal preparations and VEGFR-tyrosine kinase inhibitors for middle-advanced primary liver cancer: A systematic review and meta-analysis

BACKGROUND

This study aimed to investigate the therapeutic efficacy and safety of Traditional medicine preparations (TMPs) given in combination with vascular endothelial growth factor receptor (VEGFR)-associated multi-targeted tyrosine kinase inhibitors (TKIs) for the treatment of middle to advanced-stage primary liver cancer (PLC).

METHODS

This systematic literature survey employed 10 electronic databases and 2 clinical trial registration platforms to identify relevant studies on the use of TMPs + VEGFR-TKIs to treat patients with middle-advanced PLC. Furthermore, a meta-analysis was performed following the PRISMA guidelines using the risk ratio (RR) at 95% confidence intervals (CI) or standardized mean difference as effect measures.

RESULTS

A total of 26 studies comprising 1678 middle-advanced PLC patients were selected. The meta-analysis revealed that compared with VEGFR-TKI mono-treatment, the co-therapy of TMPs + VEGFR-TKIs considerably enhanced the objective response rate (RR = 1.49, 95% CI: 1.31-1.69), disease control rate (RR = 1.23, 95% CI: 1.16-1.30), and one-year overall survival (RR = 1.49, 95% CI: 1.28-1.74). Furthermore, the co-therapy was associated with reduced incidences of liver dysfunction (RR = 0.64, 95% CI: 0.45-0.91), proteinuria (RR = 0.43, 95% CI: 0.24-0.75), hypertension (RR = 0.66, 95% CI: 0.53-0.83), hand-foot skin reactions (RR = 0.63, 95% CI: 0.49-0.80), myelosuppression (RR = 0.63, 95% CI: 0.46-0.87), and gastrointestinal reactions (RR = 0.64, 95% CI: 0.45-0.92). Moreover, the co-therapy indicated no increase in the incidences of rash and fatigue.

CONCLUSION

This systematic analysis revealed that co-therapy with TMPs + VEGFR-TKIs has a higher effectiveness and safety profile for treating middle-advanced PLC patients. However, further validation using randomized control trials is required.

Progress on angiogenic and antiangiogenic agents in the tumor microenvironment

The development of tumors and their metastasis relies heavily on the process of angiogenesis. When the volume of a tumor expands, the resulting internal hypoxic conditions trigger the body to enhance the production of various angiogenic factors. These include vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), platelet-derived growth factor (PDGF), and transforming growth factor-α (TGF-α), all of which work together to stimulate the activation of endothelial cells and catalyze angiogenesis. Antiangiogenic therapy (AAT) aims to normalize tumor blood vessels by inhibiting these angiogenic signals. In this review, we will explore the molecular mechanisms of angiogenesis within the tumor microenvironment, discuss traditional antiangiogenic drugs along with their limitations, examine new antiangiogenic drugs and the advantages of combination therapy, and consider future research directions in the field of antiangiogenic drugs. This comprehensive overview aims to provide insights that may aid in the development of more effective anti-tumor treatments.

In-silico studies on evaluating the liver-protective effectiveness of a polyherbal formulation in preventing hepatocellular carcinoma progression

Liv-52, an herbal formulation consisting of seven distinct plants and Mandur Bhasma, is recognized for its hepatoprotective, anti-inflammatory, and antioxidant properties. To investigate the pharmacological potential of each phytochemical from these plants, we conducted ADMET analysis, molecular docking, and molecular dynamic simulations to identify potent molecules capable of inhibiting the interaction between Alpha-fetoprotein (AFP) and Cysteine aspartyl protease 3 (Caspase-3/CASP3). In our study, we have used molecular docking of all the compounds against AFP and filtered them on the basis of ADME properties. Among the compounds analyzed, (-) Syringaresinol from Solanum nigrum, exhibited good binding interactions with AFP, the highest binding free energy, and maintained stability throughout the simulation along with favorable drug likeness properties based on ADME and Toxicity analysis. These findings have strongly indicated that (-) Syringaresinol is a potential inhibitor of AFP, providing a promising therapeutic avenue for hepatocellular carcinoma (HCC) treatment by inhibiting the interaction between AFP and CASP3, thereby reinstating normal CASP3 activity. Further in vitro studies are imperative to validate the therapeutic efficacy of (-) Syringaresinol as an AFP inhibitor, potentially impeding the progression of HCC.

OBJECTIVE

The aim of this study was to investigate the efficacy and safety of the combined treatment regimen of D-TACE, HAIC, and Lenvatinib in patients with massive hepatocellular carcinoma, with the goal of providing a safer and more effective therapeutic strategy for individuals suffering from massive hepatocellular carcinoma.

MATERIALS AND METHODS

A retrospective analysis was conducted using clinical data from 118 patients with unresectable massive hepatocellular carcinoma who underwent treatment at the Interventional Department of Wuhan Union Hospital between June 2018 and December 2021. Based on the treatment approach, the patients were divided into two groups: the D-TACE + HAIC + Lenvatinib group (N = 54) and the D-TACE + Lenvatinib group (N = 64). The primary study endpoints included the objective response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) of the two groups. Additionally, the occurrence of treatment-related adverse events in both groups was considered as a secondary study endpoint.

RESULTS

Following the treatment, the D-TACE + HAIC + Lenvatinib group exhibited significantly higher ORR and DCR compared to the D-TACE + Lenvatinib group (68.5% vs. 43.8%, 90.7% vs. 73.4%, P < 0.05). Moreover, the D-TACE + HAIC + Lenvatinib group demonstrated longer mPFS and mOS in comparison to the D-TACE + Lenvatinib group (8.6 months vs. 6.6 months, P = 0.005; 19.5 months vs. 14.1 months, P < 0.001). There was no statistically significant difference in the occurrence rate of common treatment-related adverse events between the TACE + HAIC + Lenvatinib group and the D-TACE + Lenvatinib group (P > 0.05).

CONCLUSION

The combined treatment regimen of D-TACE, HAIC, and Lenvatinib demonstrated superior therapeutic efficacy and safety in managing unresectable massive hepatocellular carcinoma. This combination therapy may serve as a viable option for improving the prognosis of patients with unresectable massive hepatocellular carcinoma.

Prediction of iodine-125 seed implantation efficacy in lung cancer using an enhanced CT-based nomogram model

BACKGROUND

Lung cancer, a leading cause of death, sees variable outcomes with iodine-125 seed implantation. Predictive tools are lacking, complicating clinical decisions. This study integrates radiomics and clinical features to develop a predictive model, advancing personalized treatment.

OBJECTIVE

To construct a nomogram model combining enhanced CT image features and general clinical characteristics to evaluate the efficacy of radioactive iodine-125 seed implantation in lung cancer treatment.

METHODS

Patients who underwent lung iodine-125 seed implantation at the Nuclear Medicine Department of Xiling Campus, Yichang Central People's Hospital from January 1, 2018, to January 31, 2024, were randomly divided into a training set (73 cases) and a test set (31 cases). Radiomic features were extracted from the enhanced CT images, and optimal clinical factors were analyzed to construct clinical, radiomics, and combined models. The best model was selected and validated for its role in assessing the efficacy of iodine-125 seed implantation in lung cancer patients.

RESULTS

Three clinical features and five significant radiomic features were successfully selected, and a combined nomogram model was constructed to evaluate the efficacy of iodine-125 seed implantation in lung cancer patients. The AUC values of the model in the training and test sets were 0.95 (95% CI: 0.91-0.99) and 0.83 (95% CI: 0.69-0.98), respectively. The calibration curve demonstrated good agreement between predicted and observed values, and the decision curve indicated that the combined model outperformed the clinical or radiomics model across the majority of threshold ranges.

CONCLUSION

A combined nomogram model was successfully developed to assess the efficacy of iodine-125 seed implantation in lung cancer patients, demonstrating good clinical predictive performance and high clinical value.

Hepatic arterial infusion chemotherapy combined with systemic therapy sequentially or simultaneously for advanced hepatocellular carcinoma

BACKGROUND AND AIMS

The goal of this study was to compare the efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) combined with targeted therapy and PD-(L)1 blockade (triple therapy), either sequentially (SE) or simultaneously (SI), in the treatment of Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC).

APPROACH AND RESULTS

From January 1, 2018, to June 1, 2022, 575 patients with BCLC stage C HCC who underwent SE or SI triple therapy were retrospectively enrolled. Propensity score matching (PSM; 1:1) was performed to eliminate possible confounder imbalances across cohorts. We used the Kaplan-Meier method and a log-rank test to compare the overall survival (OS) and progression-free survival (PFS) rates between the SI and SE groups. The tumor response and the incidence of adverse events (AEs) were reported. After PSM, 182 patients in each of the two groups were matched. The median OS in the SI group was significantly longer than that in the SE group (28.8 vs. 16.1 months; P = 0.002), and the median PFS was significantly improved in the SI versus SE group (9.6 vs. 7.0 months; P = 0.01). The objective response rate based on the mRECIST was higher in the SI group (58% vs. 37%; P < 0.001). The total incidences of grade 3-4 AEs were 111/182 (60.9%) and 128/182 (70.3%) in the SE and SI groups, respectively. No grade 5 AEs were reported in either group.

CONCLUSIONS

Simultaneous HAIC plus targeted therapy and PD-(L)1 blockade significantly improved outcomes compared to the sequential regimen in patients with BCLC stage C HCC, with no unexpected AEs.

CLINICAL RELEVANCE STATEMENT

The patients who received hepatic arterial infusion chemotherapy combined with targeted therapy and PD-(L)1 blockade simultaneously have a better prognosis than those who received it sequentially.

Comparison of drug-eluting bead transarterial chemoembolization combined with apatinib versus drug-eluting bead transarterial chemoembolization for the treatment of unresectable hepatocellular carcinoma: a randomized, prospective, multicenter phase III trial

This randomized, prospective, multicenter (12 centers in China) phase III trial (Chinese Clinical Trial Registry #ChiCTR2000041170) compared drug-eluting bead transarterial chemoembolization (DEB-TACE) combined with apatinib and DEB-TACE monotherapy for patients with unresectable hepatocellular carcinoma (uHCC). Progression-free survival (PFS) was the primary endpoint. Overall survival (OS), mRECIST-based objective response rates (ORR) and disease control rates (DCR), and treatment-related adverse events (TRAEs) were secondary endpoints. Totally 243 cases were randomized, with 122 and 121 in the DEB-TACE + apatinib and DEB-TACE groups, respectively. Cases administered DEB-TACE + apatinib displayed markedly improved median PFS (7.1 months [95%CI 6.6-8.3] vs. 5.2 months [95%CI 5.0-5.9]) and OS (23.3 months [95%CI 20.7-29.6] vs. 18.9 months [95%CI 17.9-20.1] compared with those treated with DEB-TACE (both p < 0.001). Additionally, patients administered DEB-TACE + apatinib had elevated ORR (56.6% vs. 38.8%) and DCR (89.3% vs. 80.2%) versus the DEB-TACE group (both p < 0.001). Majority of TRAEs were mild and manageable. Regarding DEB-TACE-related TRAEs, the rates of hepatic artery thinning and spasms were elevated during the second DEB-TACE in cases administered DEB-TACE + apatinib vs. DEB-TACE. The commonest apatinib-related TRAEs in the DEB-TACE + apatinib group included hypertension, hand-foot syndrome, fatigue, and diarrhea. In conclusion, DEB-TACE plus apatinib demonstrates superior PFS versus DEB-TACE monotherapy in uHCC cases, maintaining a favorable safety profile with similar occurrences of AEs.

Comparison of treatment models for single primary advanced gallbladder cancer

Purpose

Treatment for advanced gallbladder cancer (GBC) remains controversial, with various recommendations regarding the choice and combination of surgery and adjuvant therapy. The present article is targeting for the exploration of optimal treatment models for advanced GBC.

Methods

AJCC (American Joint Committee on Cancer, 8th edition) stage III and stage IV GBC, were defined as advanced GBC. Patients with advanced GBC were identified using the Surveillance, Epidemiology, and End Results (SEER) database and departmental cohort. Because of the most representative, only gallbladder adenocarcinoma (GBAC) patients were selected. Based on their surgical status (No, Non-radical and Radical surgery), chemotherapy status (Chemotherapy, No chemotherapy), and radiotherapy status (Radiotherapy, No radiotherapy), treatment models were categorized. For the purposes of evaluating the treatment outcomes of various treatment models and determining the risk element for cancer-specific survival (CSS), Cox regression analysis was applied. Kaplan-Meier curves were used before and after adjusting for covariates, with log-rank tests used to analyze discrepancies between curves. Immunotherapy was analyzed using clinical data from departmental cohort. Finally, to compensate for the limitations of the database, a review examines the progress in treatment models for advanced GBC.

Results

5,154 patients aged over 18 years with solitary primary advanced GBC were identified from the SEER database. In advanced GBC patients, the treatment model has emerged as a significant prognostic factor. "Radical surgery + Chemotherapy + Radiotherapy" models maximally improved the CSS of advanced GBC before and after adjusting for covariates, while "No surgery + No chemotherapy + No radiotherapy" model had the lowest CSS. The present conclusions were supported even after subgroup analysis by AJCC stage. The efficacy of immunotherapy was demonstrated in the departmental cohort analysis. Additionally, this article provides a comprehensive overview of recent advancements in various emerging treatment strategies.

Conclusion

Even when optimal treatment model cannot be pursued, providing comprehensive combinations of treatments to advanced GBC patients whenever possible is always beneficial for their survival.

Prognostic Prediction and Risk Stratification of Transarterial Chemoembolization Combined with Targeted Therapy and Immunotherapy for Unresectable Hepatocellular Carcinoma: A Dual-Center Study

PURPOSE

The combination of transarterial chemoembolization, molecular targeted therapy, and immunotherapy (triple therapy) has shown promising outcomes in the treatment of unresectable hepatocellular carcinoma (HCC). This study aimed to build a prognostic model to identify patients who could benefit from triple therapy.

PATIENTS AND METHODS

This retrospective study encompassed 242 patients with HCC who underwent triple therapy from two centers (Training cohort: 158 patients from the Center 1; External validation cohort: 84 patients from the Center 2). Independent predictors of overall survival (OS) and progression-free survival (PFS) were identified through Cox regression analyses, and prognostic models based on Cox proportional hazards models were developed. Prognosis was assessed using Kaplan - Meier curves.

RESULTS

In the training cohort, independent predictors of PFS included vascular invasion and the C-reactive protein and alpha-fetoprotein in immunotherapy (CRAFITY) score. Independent predictors of OS were the CRAFITY score, extrahepatic metastasis, and the neutrophil-to-lymphocyte ratio. Prognostic prediction models were constructed based on these variables. The prognostic model for OS demonstrated a C-index of 0.715 (95% confidence interval (CI), 0.662-0.768) in the training cohort and 0.701 (95% CI, 0.628-0.774) in the validation cohort. Patients were divided into low- and high-risk categories using the predictive model (P<0.001). These findings were corroborated by the external validation cohort.

CONCLUSION

The developed prognostic model serves as a reliable and convenient tool to predict outcomes in patients with unresectable HCC undergoing triple therapy. It aids clinicians in making informed treatment decisions.

Development and validation of a risk predictive nomogram for colon cancer-specific mortality: a competing risk model based on the SEER database

BACKGROUND

Utilizing the SEER database, we developed a competing risk model along with a nomogram designed for the early identification of colon cancer-specific mortality (CSM) risk.

METHODS

Clinical and pathological information, along with other significant data, were obtained from the SEER database. Patients were randomly divided into a training set and a validation set. We investigated the independent factors affecting CSM among colon cancer patients using univariate and multivariate analyses within a competing risk framework, ultimately developing a predictive tool for CSM in colon cancer.

RESULTS

Involving 40,261 individuals diagnosed with colon cancer, our study included 10,397 deaths directly due to the disease and an additional 5,828 from other causes. We used a competing risk model to predict cancer-specific mortality (CSM) in these patients. For the training dataset, the model's area under the curve (AUC) for predicting 1-, 3-, and 5-year cancer-specific survival (CSS) was 0.835 (95% confidence interval [CI] 0.826 to 0.844), 0.849 (95% CI 0.843 to 0.855), and 0.843 (95% CI 0.836 to 0.850), respectively. In the validation group, the AUC values for the same time periods were 0.846 (95% CI 0.833 to 0.860), 0.853 (95% CI 0.843 to 0.862), and 0.846 (95% CI 0.835 to 0.856), respectively. In comparison, traditional survival analysis yielded higher cumulative CSM rates over time than those provided by our competing risk approach.

CONCLUSION

We created a competitive risk assessment model along with a predictive tool designed to estimate CSM in patients with colon cancer. This nomogram demonstrates high accuracy and reliability, aiding medical professionals in making clinical decisions and developing patient follow-up plans.

Locoregional Therapies for Hepatocellular Carcinoma: A Systematic Review and Meta-Analysis

Importance

Several locoregional therapies (LRTs) for nonmetastatic hepatocellular carcinoma (HCC) are available; however, a global comparison of the relative efficacy of each is needed.

Objective

To conduct a systematic review and direct, pairwise meta-analytic comparison of all identified randomized clinical trials evaluating the treatment of nonmetastatic HCC.

Data Sources

A comprehensive search of PubMed and the proceedings of the American Society of Clinical Oncology and American Society for Radiation Oncology annual meetings from January 1, 2010, to November 1, 2023, was performed.

Study Selection

Randomized clinical trials using a form of LRT (surgery with or without adjuvant therapy, radiofrequency ablation [RFA], microwave ablation [MWA], radiotherapy [RT], hepatic arterial infusion chemotherapy [HAIC], transarterial bland embolization [TAE], transarterial chemoembolization [TACE], or transarterial radioembolization [TARE]).

Data Extraction and Synthesis

Study eligibility and data extraction were each reviewed by 2 authors independently. Random-effects meta-analyses were used to compare treatment categories.

Main Outcomes and Measures

Progression-free survival (PFS) was the primary outcome; overall survival (OS) was the secondary outcome.

Results

Forty randomized clinical trials reporting on comparative outcomes of 11 576 total patients with localized HCC treated with LRT were included. The median follow-up was 30.0 (IQR, 18.5-40.8) months. Direct pooled comparisons between treatment classes suggested improved outcomes for surgery combined with adjuvant therapy over surgery alone (PFS: hazard ratio [HR], 0.62 [95% CI, 0.51-0.75]; P < .001; OS: HR, 0.61 [95% CI, 0.48-0.78]; P < .001), surgery over RFA (PFS: HR, 0.74 [95% CI, 0.63-0.87]; P < .001; OS: HR, 0.71 [95% CI, 0.54-0.95]; P = .02), RT over TACE (PFS: HR, 0.35 [95% CI, 0.21-0.60]; P < .001; OS: HR, 0.35 [95% CI, 0.13-0.97]; P = .04), and HAIC over TACE (PFS: HR, 0.57 [95% CI, 0.45-0.72]; P < .001; OS: HR, 0.58 [95% CI, 0.45-0.75]; P < .001). No substantial heterogeneity was noted for any pairwise comparison with the exception of RT-based regimens compared with tyrosine kinase inhibitor therapy.

Conclusions and Relevance

The findings of this systematic review and direct, pairwise meta-analysis suggest that all LRTs are not equivalent for the treatment of localized HCC. The efficacy of LRTs appears hierarchical, with surgery-based management outcomes associated with the best treatment outcomes and embolization-based treatment options associated with the worst treatment outcomes.

Advancements in nano drug delivery system for liver cancer therapy based on mitochondria-targeting

Based on poor efficacy and non-specific toxic side effects of conventional drug therapy for liver cancer, nano-based drug delivery system (NDDS) offers the advantage of drug targeting delivery. Subcellular targeting of nanomedicines on this basis enables more precise and effective termination of tumor cells. Mitochondria, as the crucial cell powerhouse, possesses distinctive physical and chemical properties in hepatoma cells different from that in hepatic cells, and controls apoptosis, tumor metastasis, and cellular drug resistance in hepatoma cells through metabolism and dynamics, which serves as a good choice for drug targeting delivery. Thus, mitochondria-targeting NDDS have become a recent research focus, showcasing the design of cationic nanoparticles, metal nanoparticles, mitochondrial peptide modification and so on. Although many studies have shown good results regarding anti-tumor efficacy, it is a long way to go before the successful translation of clinical application. Based on these, we summarized the specificity and importance of mitochondria in hepatoma cells, and reviewed the current mitochondria-targeting NDDS for liver cancer therapy, aiming to provide a better understanding for current development process, strengths and weaknesses of mitochondria-targeting NDDS as well as informing subsequent improvements and developments.

Analysis of complications of giant gastric ulcers induced by hepatic arterial infusion chemotherapy or combined immunotherapy: A report of three cases

Primary liver cancer is a major public health issue in China, with high incidence and mortality rates. Notably, progress has been made in improving the surgical methods and hepatic arterial infusion chemotherapy (HAIC) regimens of liver cancer and the combination of HAIC with immunotherapy is expected to further increase the surgical conversion rate or objective response rate. However, patients with liver cancer often have underlying cirrhosis, which may lead to complications, such as esophageal varices and high-pressure gastric diseases. The present study describes three cases of giant gastric ulcers that occurred during the process of HAIC or combined immunotherapy. Notably, the causal relationship between HAIC and immunotherapy is unclear. In patients with tumors receiving immunotherapy, gastrointestinal adverse reactions are common, and some may develop serious complications, such as gastrointestinal perforation. The present study provides a detailed analysis of this issue and emphasizes the need for further clarification of its mechanisms and effective treatment methods.

Expert consensus on perioperative management for liver tumors treated with co-ablation system therapy

Co-ablation system therapy is currently in its early stages of application in tumor treatment in China. The associated protocols for perioperative management are not yet well-developed and suffer from a lack of corresponding guidelines or consensus. This study aims to improve the quality of clinical treatment and nursing care and to standardize perioperative management for patients with liver tumors undergoing co-ablation system therapy. The Committee of Ablation Therapy in Oncology, China Anti-Cancer Association, and the Committee of Interventional Perioperative, Interventional Physician Branch of the Chinese Medical Doctor Association organized medical and nursing experts in China. Based on the clinical practice of co-ablation system therapy in China and the relevant domestic literature, an expert consensus regarding perioperative management was developed. The expert consensus includes the key points of perioperative management, prevention and care of complications, discharge guidance, and follow-up management for patients who have undergone co-ablation system therapy of liver tumors. The consensus on the perioperative management of co-ablation system therapy for liver tumors has finally been formulated, providing a reference and application for medical personnel in relevant fields based on hospital and patient conditions in clinical work.

Clinical Effectiveness and Safety of Transarterial Chemoembolization: Hepatic Artery Infusion Chemotherapy Plus Tyrosine Kinase Inhibitors With or Without Programmed Cell Death Protein-1 Inhibitors for Unresectable Hepatocellular Carcinoma-A Retrospective Study

BACKGROUND

Locoregional treatment with transarterial chemoembolization (TACE) or hepatic artery infusion chemotherapy (HAIC) and systemic targeted immunotherapy with tyrosine kinase inhibitors (TKI) and programmed cell death protein-1 (PD-1) inhibitors in the treatment of unresectable hepatocellular carcinoma (uHCC) have achieved promising efficacy. The retrospective study aimed to evaluate the efficacy and safety of TACE and HAIC plus TKI with or without PD-1 for uHCC.

PATIENTS AND METHODS

From November 2020 to February 2024, the data of 44 patients who received TACE-HAIC + TKI + PD-1 (THKP group) and 34 patients who received TACE-HAIC + TKI (THK group) were retrospectively analyzed. Primary outcomes were overall survival (OS) and progress-free survival (PFS), and secondary outcomes were objective response rate (ORR), disease control rate (DCR), conversion rates, and adverse events (AEs).

RESULTS

A total of 78 patients were recruited in our single-center study. The patients in THKP group had prolonged median OS [25 months, 95% confidence interval (CI) 24.0-26.0 vs 18 months, 95% CI 16.1-19.9; p = 0.000278], median PFS [16 months, 95% CI 14.1-17.9 vs 12 months 95% CI 9.6-14.4; p = 0.004] and higher ORR (38.6% vs 23.5%, p = 0. 156) and DCR (88.6% vs 64.7%, p = 0.011) compared with those in THK group. Multivariate analysis showed that treatment option and alpha-fetoprotein (AFP) level were independent prognostic factors of OS and PFS. The frequency of AEs were similar between the two groups.

CONCLUSIONS

The THKP group had better efficacy for uHCC than the THK group, with acceptable safety.
